Abstract

Orbital myositis is a common cause of extraocular muscle enlargement. It is characterized by nonspecific inflammation of one or more extraocular muscles. Although often idiopathic in origin, orbital myositis has been associated with various noninfectious diseases. Several cases have also been reported as occurring after upper respiratory tract infections. The present report describes a case of orbital myositis together with subclinical sinusitis and its rapid resolution after antibiotic treatment. The literature on this clinical entity is also reviewed.

Keywords: Myositis; Ocular muscle infection; Sinusitis.
